<p>The circuit has a planar active winding (L1) connected between two access terminals (A1, A2), and an auxiliary winding arranged coplanar with the active winding, where an end of the auxiliary winding is connected to one of the access terminals. A tuning capacitor (C) is connected to another end of the auxiliary winding, where turns of the active and auxiliary windings are interleaved. Two parts (L2a, L2b) of the turns of the auxiliary winding are arranged inside and outside the active winding, respectively. A group of distinct turns interleaved with turns of another auxiliary winding. Independent claims are also included for the following: (1) a passive near-field communication device (2) an active near-field communication device.</p> |
